[flexcoders] How do I make this custom Style property work correctly?
I'm trying to create a CSS style property that expects an mx:Effect
object to be used in a custom AS class. I want to detect changes being
made to the style property and assign the specified effect to an effect
trigger belonging to a child of my custom component.
Unfortunately, the specified mx:Effect object seems to be interpreted as
a string instead of an mx:Effect object. Can anyone tell me what I need
to correct for this to work as expected?
You can see the compiled example here
http://tommyb.com/flex/styleeffectbug/index.html and review the
source code below. It fails due to a TypeError: Error #1034: Type
Coercion failed: cannot convert myTestEffect to
mx.effects.Effect.Style in the custom components styleChanged function
at the bottom of this post.

[flexcoders] Re: Custom Tooltips in actionscript - Correction
John,
Thanks for the tips. I think I got it between your help and one spot
in the UIComponent help. So the code I was getting caught up in was
the line
toolTipCreate=event.toolTip=this.createTip()
Where createTip created a custom tooltip as described in a number of
posts I've seen before. What I failed to understand was that the code
is really a small function and equivalent to:
onInit(): void{
...
chkbox1.addEventListener(ToolTipEvent.TOOL_TIP_CREATE, onToolTipCreate);
}
private function onToolTipCreate(thisEvent : ToolTipEvent): void {
thisEvent.toolTip = this.createTip();
trace(ToolTipCreate);
}
So I was able to get this model to display my custom tooltips for my
subset of items. On the TOOL_TIP_SHOW event, I can initialize the
tooltip components.
Thanks for your help,
Rich

[flexcoders] resizing the datagrid ?
Hi , I facing a lot of problem for resizing the datagrid. I have created a datagrid component which I am placing in a HBox. I have to set the size of datagrid in percentage to make it resizable. Can anyone tell me what properties of datagrid can I set in percentage, I need to keep rowcount constant, that means rowheight will vary, now if I set pecentageHeight to some value say 90%, it calculates the rowheight and also the rowcount on it's own, so sometimes I get a extra empty row at the bottom and sometimes the last row appears half.

Is there something else I can do to get code-hinting to work again? Thanks, Bruce
[flexcoders] Data binding nested data??? BUG???
All,
Does anyone understand why this databinding doesn't work. It seems
like this is a significant bug.
Example shows a form with several fields, a data model, bindings, a
grid and a second form to echo the data. Clearly the bindings work
as the second form echos the first, the top level objects, email and
description also work, it's the nested objects that don't work on the
grid.
This the datagrid does work as I would I would expect:
Any thoughts would be appreciated.

RE: [flexcoders] resizing the datagrid ?
I ended up having to calculate out the datagrid height after I populated
it... the code looked something like this:
populateGrid(event:ResultEvent):void {
acGridData = event.resut as ArrayCollection;
callLater(resizeGrid);
}
resizeGrid():void {
myGrid.height =
myGrid.measureHeightOfItems(-1,myGrid.dataProvider.length + 1);
}
I also had to set myGrid's verticalScrollPolicy = off
I had to callLater because the calculation was always wrong otherwise.

[flexcoders] best way to do database to Java to XML to flex
I have been using remoting to get data out of my database and into flex. The nice thing about this is it handles all the data conversion issues etc. But now, I have a need to be able to communicate certain data in XML format. I would imagine that there must be a clean process/format for communicating between server and client in XML such that the datatypes and reserved characters such as ,',,, are handled. what is the easiest way of doing this? Is there some XML database communications standard which flex can read? Do people just roll their own (ugh?). There must be a clean easy way to do this. Hank
[flexcoders] How to implement Lazy Hibernate?
Hi All, I'm attempting to create a Cairngorm/FDMS/Hibernate/MySQL example program which I'll publish to the community once completed. I used the MySQL Sakila sample DB (pared down to 3 tables - Film, Actor FilmActor - at present) and used HibernateTools to reverse engineer the requisite Java and Hibernate files. So far, so good. I've even managed to successfully write corresponding .as files and implement the beginnings of a Cairngorm front end. And it works. Kind of. The problem is that the persistence layer takes forever to load, even though the 3 tables only have hundreds or thousands of records each. I've temporarily pared them down considerably (to 100, 100 500 records) and the program now loads quickly enough that I can continue development work, but the performance issue needs to be addressed.

The DB's schema is outlined here: http://www.brightwo http://www.brightworks.com/technology/tech_questions/hibernate_lazy_associa tions/index.html rks.com/technology/tech_questions/hibernate_lazy_associations/index.html And all relevant code, plus my latest error message, is here: http://www.brightwo http://www.brightworks.com/technology/tech_questions/hibernate_lazy_associa tions/code.txt rks.com/technology/tech_questions/hibernate_lazy_associations/code.txt I assume that my problem is in data-management-config.xml, but I'm new to all of this and could be doing other things wrong as well.

[flexcoders] Re: Initial order column for DataGrid - Flex2
You should try to sort the ArrayCollection that is bound to the dataGrid's dataProvider. Once the collection or the source array is sorted, your data grid will be sorted. Kim --- In flexcoders@yahoogroups.com, kehlpeter [EMAIL PROTECTED] wrote: Hi, is there any way to set a default/initial order column for a DataGrid in Flex2? None of the following compiles in Flex 2: grid.sortItemsBy( 'columnName', 'asc'); grid.sortIndex= 1; grid.sortDirection= 'ASC'; grid.placeSortArrow(); I can't see any method/property to do this directly. I know how to create a DataGridEvent with type being DataGridEvent.HEADER_RELEASE, but don't know how to 'trigger' or dispatch it. I've tried dispatchEvent( event ) in both application.creationComplete and grid.initialize. Thank you for any ideas.
[flexcoders] head namespace in Flex 2 Style Explorer
Hi guys, I've been looking into the Flex 2 Style Explorer at http://examples.adobe.com/flex2/consulting/styleexplorer/Flex2StyleExplorer.html and have a question about the head namespace used in the example. Could someone point out where in the code that namespace is being declared? For example, there is a reference to head:GlassHeaders all over the place, but I cannot understand how head is resolved. Does it have a special meaning? What am I missing here? Thanks, Mark
[flexcoders] DataBinding Vs. Procedural Model Updates
Hi All,
Anyone know the performance implications of using databinding to
update a model vs an 'updateModel()' type call?
I can use basic databinding to bind a form to the model
(source={foo.customer_name}) and databinding calls to bind
foo.customer_name back to the form control (so your model is updated
everytime a form field is updated). This has the advantage that your
model is always up to date with respect to the form - no extra
processing required.
I could also just use the basic databinding to bind the form controls
to the model, and an UpdateModel(m:Model) call to grab the contents of
all the fields and shove them back into the model. This requires an
extra function call to 'sync' the model with the form, but skips all
the event handling (for instance, if you update the 'customer_name'
control 3 times, you only update the model once at the end)
Anyone know how much of a load data binding/event processing puts on
the system with a moderately complicated app? I'm figuring 10-20
tables of 20-40 fields each. This is for a data entry app, so users
will be in all parts of the app all day long. Should I be looking at
un-binding models when they are not used/active (ie, if you switch
from clients to vendors, should I unbind the fields on the 'clients'
model ?)

[flexcoders] padding in the text in cells in a datagrid
Hi , How to give padding to text in the cells. In my datagrid I have numbers which are right aligned, but they are too much right aligned, the text in last column touches the scroll bar. Can I have padding in the text?
[flexcoders] drawing a stack of rectangle ?
Hi, I am drawing a stack which contans rectangles of different depending on some value. rectangles are drawn but they are overlapping each other by 1 or 2 pixels at the end. I have to highlight the rectangles also, for that I am creating a rectangle on mouseOver event and adding the rectangle on the same rectangle that I am highlighting, but this way the lower border of the highlighter gets covered by the rectangle below that.
